I personally LOVE public affection. Things like my guy putting his arm around my waist, holding my hand, and kisses on the cheek...A good place for it : mall, movies, park, beach. I adore both giving and receiving-doesn't bother me a bit :p The only thing I find inapropriate are touching of the breasts, private parts, or getting really steamy in front of kids and the elderly-that's a no-no :D

Doing things you'd normally do in private, in public. Like making out, gazing mushily at each other, etc...

What things/actions do you consider to be public intimacy?

See above.

What things/actions do you consider to be appropriate/inappropriate expressions of public intimacy?

Depends on what part of public you mean. In the movie theaters it's more acceptable to be kissing (though farther than making out is pretty inappropriate/gross). While in crowded public places, nothing more than a kiss on the lips and holding hands.

Do you like to give/ receive expressions of public intimacy?

No. I hate it if it's beyond holding hands or kissing. I only tolerate it because my partner loves it.

what are some good locations are to give/ receive expressions of public intimacy?
